Abstract: 1,093,214. Feeding sheets. LEIPZIGER BUCHBINDEREIMASCHINENWERKE VEB. Feb. 23, 1965, No. 7791/65. Heading B6B. In apparatus in which folded sheets 9 are opened and dropped on to an inverted V-shaped saddle 1, Fig. 1, along which they are conveyed to e.g. a stitching machine, one or more feeler switches 7, 8 in parallel are provided at each side of the saddle 1 so that if a sheet is absent, or both parts of the folder sheet pass to one side of the saddle, or the sheet is defective, the machine is stopped. The sheets are fed by grippers 5 on chains 4 and pass under a deflector plate 6. Each gripper engages the free end of one of the parts of the sheet and moves that part over a chain wheel so as to cause the sheet to be opened. As shown in Fig. 2, the switches 7, 8 are in series with a switch 10 and a machinestopping relay 11, the switch 10 being closed during that part of the machine cycle when a sheet should be positioned on the saddle. If the sheet feed to the saddle is defective, one or both of the switches close during the period the switch 10 is closed and the relay 11 is operated to stop the machine. If the stitching machine requires an idling cycle between the stitching of two consecutive books, no sheet is fed during this cycle, and to avoid the stopping of the machine, a switch 17 is operated to open the circuit of the relay 11 during this cycle. Two or more switches, i.e. 13, 14 and 15, 16, Fig. 3 (not shown), may be provided at each side of the saddle so as to cause the machine to be stopped if, for example, a sheet corner is turned over.

Abstract: 1452255 Making sand moulds and cores SANTEC MFG Inc 25 Feb 1975 [25 Feb 1974 5 Dec 1974] 7847/75 Heading B3G Apparatus for the production of sand moulds or cores comprises an endless chain conveyer 15 mounting a number of mould flasks 17 with attached patterns 22 fed, in turn, with a sandbinder-mixture from a hopper 27 supplied via a screw mixer 34; the mixture is compacted by a vibrator 36 at the sand-filling station and is further compacted by a pressure plate 44 which may include means for introducing a gas for curing the binder. The plate 44 traverses a rod 45 during the compaction; further curing may be effected by an infra-red heater 46 after which a roller brush 47 sweeps away loose sand. On flask inversion at the end of the conveyer upper run the flask tops are brought into abutment with a second conveyer 48 on to which the sand moulds are transferred after being subjected to a vibrator 61. One end of the conveyer 48 is pressed against the flasks by rollers at the ends of pivoted links 58 acted on by weights 60; alternatively the roller system alone may act on the moulds during flask inversion, in which case the conveyer 48 extends merely horizontally. In a further embodiment a conveyer separate from the conveyer 48 is in association with the roller system. During the return run of the main conveyer the flasks are raised relative thereto and away from the conveyer 48 to separate them from the moulds; such movement is effected by a stationary inclined ramp 26 which is engaged by rollers 19, 20 on the flasks. The emptied flasks are cleaned by an air nozzle 65 and sprayed with a mould release agent by a means 66. The flasks have flanges at their upper ends which abut during their travel, and surplus sand from one flask is directly transferred to the succeeding one by a reciprocating scraper 38 guided by a wheel 38 and driven by pneumatic means 41; a piston means 40 tilts the scraper for its return movement over a flask.

Abstract: 799,109. Pit props. BECORIT-GRUBENAUSBAU GES. March 22, 1955, No. 8277/55. Class 20(2) In a telescopic prop, the outer member 2, Fig. 5, carries a lock in the form of an elongated ring-like member 3 the two longer sides of which Can be transversely flexed to draw the shorter sides inwardly to impart a locking thrust against pressure members 4, 5, engaging the inner prop member 1. In Figs. 5 and 6 wedge shaped tensioning elements 7 are adapted to be forced upwardly by a transverse wedge 8 bearing on the outer member 2 in order to cutwardly flex the longer sides of the member 3 when the lock is to be tightened. The inner prop member 1 comprises two parts between which a friction insert 6 having wedge surfaces 6a is adapted to co-operate with wedge surfaces 6b on the tensioning elements 7, whereby the insert 6 functions in the manner of a drag wedge to effect additional tightening of the lock as the prop yields. In another embodiment, Figs. 3 and 4 (not shown), also having tensioning members interiorly arranged within the member 3, a friction insert is provided which does not function as a drag wedge. In a further embodiment, Fig. 7, the longer sides of the member 3 are engaged exteriorly by stirrup members 17 projecting from the friction insert 6. The longer sides, of the member 3 are inwardly flexed to tighten the lock with the aid of a vertical wedge 17a guided in one of the stirrup members 17. The friction insert can be arranged to function as a drag wedge by inclining the faces of the stirrups 17 bearing upon the long sides of the member 3 so that they increasingly press these side members inwardly as the insert 6 is dragged along by the inner prop member 1. The member 3 may be of vertically tapering shape and may comprise sides connected to ends by hinges or may be formed of circularly or spirally wound wire cables or steel wires or may be formed of a plurality of spring _strips arranged in layers one over the other. The sliding surfaces may be provided with friction linings.
